Since this snippet includes a lot of information the title is simply a bunch of keywords. Basically we are using file uri to determine if it exists and is managed or needs to be saved as new managed file. Then use "entity_metadata_wrapper" to save the field to entity. This example is from migration of files from another Drupal installation.
